Notice: Brushless electric motors & ESCs have huge amounts of torque at any given RPM. Using too-tall gearing, or a vehicle that is too large/heavy, can result in damage and/or product failure. Please consult your manual and select gearing suitable for the vehicle and terrain, as damage caused by overloading or abuse is unlikely to be covered by the manufacturer's warranty. Always monitor your ESC and motor temperatures closely after modifying your system to ensure they stay within the safe operating limits.

The Hobbywing XR10 Justock G3 Sensored Brushless ESC/SD G2.1 Motor Combo has been designed with fixed, 0°, timing for spec class racing.

  • Programmable via OTA Bluetooth module or 3in1 program box
  • Built-in capacitor module eliminates the need for external capacitors and unwanted space
  • RPM speed limit function supports up to 6 different speed, RPM, selections to meet the needs and demands of various competitions in the world (Set through OTA module or 3in1 box)
  • Internal ESC timing has been set to 0 degrees and cannot be adjusted for stock racing
  • Built-in BEC can support a maximum output current of up to 8A. Output voltage can be set between 6V or 7.4V
  • Calibration or preforming a factory-reset can be achieved by using this SET button. Simple and easy to use
  • Supports both CCW (counterclockwise) and CW (clockwise) motor directions
  • Protection functions include: reverse polarity, battery voltage, ESC temperature, motor temperature, signal lost and locked rotor protection
  • Supports ESC firmware upgrades
  • User-friendly and convenient for set-up
  • Use of a heat-resistant magnet attached aluminium case and double insulated windings, high precision bearings, and rotor with a strong structure guarantees outstanding performance and super durability
  • Built-in Hall sensor non-adjustable end bell combined with a high precision and balanced rotor guarantees the user a smooth and linear power on demand
  • Silicon O-ring seal fitted between the end bell and stator helps to conduct inner heat to the motor case and prevent dust from entering the HALL sensor
